What happens when this plastic surface is wet?

Re" what happens when the plastic surface gets wet".
In 1972 I experienced this on my moped in Copenhagen. The moped slipped on a painted stripe and I went down in front of a bus. Luckily the bus managed to stop.
In Modern Copenhagen, Bikes and cars are seperated. You can study the standard construction modes in Copenhagen from the "vejdirektoratet" in this link- http://www.vejregler.dk/pls/vrdad/vr_layout.vis?p_gren_id=2707
